Question

What is the hydrogen ion concentration in molarity if the hydroxide ion concentration is 7.609 10-13 ?

[H+][OH-] = 10-14
pH = -log[H+]
[H] = 10pH

Answer 1

Answer: The hydrogen ion concentration in molarity is 0.013

Step-by-step explanation:

pH or pOH is the measure of acidity or alkalinity of a solution.

pOH is calculated by taking negative logarithm of hydroxide ion concentration and pH is calculated by taking negative logarithm of hydrogen ion concentration

Putting in the values:

`pOH=-\log[7.609* 10^(-13)]`

`pOH=12.1`

Now ,
`pH+pOH=14`

`pH=14-12.1=1.9`

`pH=-\log [H^+]`

`[H^+]=0.013M`

The hydrogen ion concentration in molarity is 0.013
